Abstract (en)

[origin: JP2018021913A] PROBLEM TO BE SOLVED: To provide an encoder which can perform signal transmission of a signal error early.SOLUTION: An encoder 10 includes: a scale carrier 14 having one measurement scale; a scanner 12 relatively movably arranged in one measurement direction with respect to the measurement scale for generating scanning signals S0, S90, R depending on a position by scanning the measurement scale; a signal processor 20 for processing the scanning signals to position signals; and a signal interface 50 capable of outputting the position signals to one subsequent electronic equipment. At least one of correction devices 20.1, 20.2, 20.3 and one monitoring device 30 are arranged within the signal processor, and at least one signal error of at least one scanning signal can be corrected by a correction device, arrival of one limit value of the signal error can be checked by the monitoring device and after that, the correction device causing at least the event can be inactivated.SELECTED DRAWING: Figure 1
